The Hawaiian forester and agriculturist . a spore thathas swollen and become somewhat sphericalpreparatory to germination ; e. a spore thathas become spherical and started to sendforth mycelium at the left hand side; /,three spores a stage farther advanced thanthat at e, these three spores being part ofthe same chain as that marked d. but allnow separated; g, two spores still fartheradvanced than those at /, one of them hav-ing started to branch at a much earlierstage than is usual with this species; h, h,spore whose hypha has one septum: i. i,spore whose hypha has two septa: ;, threespores still attached to each other that havenevertheless germinated. The spores a, b. c, have been mountedin water and drawn at once. The remain-ing spores have been passed through thefly Eristalis punctidatus. a common Syrphidfly ,and afterward germinated in pineapplejuice. The passage through the fly makesno difference in the germination of thespores. The spores a to e would, if placedin pineapple juice, germinate in preciselythe same macrospore of Tliiclaziopsis is somewhat below these dimen-sions. At any rate, tlie spores are mgested by various com-mon species of flies belonging to the Muscidae, Sarcophagidaeand Syrphidae. All the species 1 have tried are such as nor-mally search out and prefer saccharine food. These take inthe Thielaviopsis spores with sugar solutions artificiallv pre-pared as described, and the spores pass through the insectswith little if any apparent alteration. From one to a dozenor more spores are to be found in each portion of excrement 134
